5515-5517 California St, San Francisco, CA 94121

The property at 5515-5517 California Street is a two-unit, two-story multi-family residential building with commercial space, constructed in 1914 and currently owned by King Chiu & Ow Siu Hing Cha. The building has experienced several significant infrastructure issues over the past decade, most notably a series of six sewage backup incidents between January and April 2015 that required intervention from PUC Sewer Operations, all of which were eventually resolved.

A more recent plumbing infrastructure upgrade occurred in 2011 with the replacement of the water service line. The building's maintenance history includes a completed aluminum window installation in 1985 and reroofing work performed in 1994, though the latter permit has since expired. The property has been subject to various enforcement and complaint matters, including a significant incident in 2015 when it was identified as being used for unauthorized cannabis oil distribution, which was subsequently abated.

There was also a fire complaint in September 2015 that was resolved within nine days. More recent incidents have been primarily related to street-level issues, including two reports of abandoned vehicles (in 2024 and 2021) and a loose garbage cleanup in 2022, none of which directly impacted the building's habitability or safety. While the building experienced recurring sewer issues in 2015, these appear to have been resolved, with no similar complaints reported in the subsequent years to date.
